I never have ridden BlaBlaCar either, though they have it here in Mexico. However, taking buses to go between cities is a world of difference from Greyhound. Larger seats, more legroom, movies shown on board / personal monitors at every seat, complimentary lunch when you board, fleet is more state-of-the-art.

The concept behind blablacar was that the driver was already going from one city to another so they could take on passengers and get some gas money. It has changed from that to most drivers doing it commercially like a taxi and if they don't get enough passengers to justify the trip they will cancel the ride or charge you more.
